Whats the best pinion for 1700 and 1800 headspead

Which pinion would be best 11t or 12t

Cc edge 80hv and 3300 mah packs 12s

You can use this calculator here to find out:

Some ESCs need to run at a high percentage, so you'll need to read your manual to find out what is best.

Yup depends on your ESC, and the flight pack 10S is going to need taller pinion, 12S not so much...

As a direct answer the 11T will be best but for a 12S setup a 450Kv motor would be better.

Billyboy, try the 10t mod 1.0 pinion first.

It will run just over 2000rpm with the Castle (120?) and 700mx.

I'm not sure why you want 17-1800rpm, but check this out...

This is a small motor in a Logo 600 at 2000rpm:

Watch at YouTube

That heli was 8lbs, yours is 9lbs.

The big motors are dead-weight until 22-2300rpm, theyre good for spinning those rpms.

You could fly a Logo 600 on just one of your 6s 3300mah packs and fly with a 4025-890 scorpion motor....not joking.

The flying weight would be around 7 lbs. It will fly about half as hard as that video on a 3300mah and go through those packs in a few months. BUT the same motor with a 5000mah battery would outperform that video and the packs would last a while.

(that setup in the video was an actor 24-3 with a 4000mah 10s pack. It is 11 ounces heavier than a 6s 4500mah Logo 600)

I'm building a 7 lb 10s Logo 550se at the moment

trying a 470 kv 700mx and 11t pinion
Im just enjoying sport flying and mild 3d anybody think this would be good for low head flying
Posted by KC on 03-16-2015 04:11 AM:
That or the 510kv with the 10t pinion will be great for sport and mild 3d.

Do you have either 700mx motor at the moment?

trying a 470 kv 700mx and 11t pinion
I have a 700mx 510kv and 12t pinion on it now got a deeal on a 700mx 470kv and 11t pinion on the way see which combo I like best
Posted by KC on 03-16-2015 05:05 AM:

sounds like you tried the higher rpms then...

Try the 10t pinion too.

Are you sure Mikado make a 10T mod 1 pinion for a 6mm shaft?

I don't think there is enough metal at the centre for one.
Posted by billyboy on 03-17-2015 03:15 AM:
mikado pinion
Mikado dont make a 10t pinion in 6mm as far as I know
Posted by KC on 03-17-2015 03:29 AM:
I must have been smoking something guys...4 years ago I could swear they had a 10t mod 1 (didn't think about whether it was 5 or 6mm)

I can't find it on the US or German site.

disregard the 10t!
